My new workstation runs RH Release 6.6 with Linux kernel 2.6.32-504.el6.x86_64, with a Xeon CPU & 64 GB RAM, etc. Nothing else is different, however, now my Fortran routines with openMP calls to the BLAS lib (from Intel Libs) aren't maximizing core/thread usage (it looks like core/thread-swapping has gone "nutz") unless I set the number of threads to 1 in my execution script. Have you seen this behavior with upgrades to the multicore/multithread CPUs?
